Be it knownv that I, LUTHER C. CRowELL, a citizen of the United States, residing at Brook- -lyn, county of Kings, and State of New York,

A ings, forming apart of the same. I

In newspaper printing it is often desirable to print a paper or part of a paper in colors, while it is undesirable to further increase the size and complication of rapid web printing machines by additional printing mechanisms for such color printing, and the cost of such machines of high capacity and the extra floor space required, prevent the general use of separate color printing machines. In all printing oifices, moreover, in which multicolor printing is ever desirable, the advantages of a construction enabling such color printing from printing mechanisms the full capacity of which is available for web perfecting, will readily be recognized.

The object of the present invention is to provide an improved construction of web printing machines by which the full capacity of the printing devices may be utilized for web perfecting or multiple impressions for color printing be taken therefrom, and I attain this object by combining with a plurality of web printing mechanisms capacitated to print and perfectaplurality of webs,

web controlling devices co-acting therewithv to-present-a web of less width than the capacity of the printing surfaces to different portions of theprinting surface of some or all of the printing devices, so that the printing mechanisms may be used for perfecting a plurality of fullwidth webs or printing in colors on a web ofless thanfull width as desired.

While I claim such a combination broadly,

and my invention ineludesa construction in whichaplurality of web printing mechanisms are combined with web controlling devices so as to print and perfect a plurality of webs or to cO-actin printing in multiple 1m- 1 pressionson a web of less than fullwidth,

whether upon asingle such narrow web or a abled to provide a construction which will I print and perfect a plurality of full width webs at high rates of speed, or may be used to produce at correspondingly high rates of speed the most desirable products in color printing, and under my inventionI intend to include also, broadly, such a construction.

It is evident that my invention broadly considered may be applied in connection'with web printing mechanisms of any suitable form, that the web controlling, devicesfor guiding the web for color printing may be of any suitable construction, and that many different arrangements of the two may be made in'accordance with the result desired.

In the accompanying drawings forming a part of this specification, I have shown constructions embodying my invention in two of the preferred forms, certain features in which constitute specificparjts of my invention, and from a detailed description of these constructions, the application of my invention in other constructions will be obvious to those skilled in the art.

In the drawings: Figure 1 is a longitudinal sectional diagram taken inside the frame of a construction embodying my invention in one of its preferred forms, as applied in connection with two web perfecting mechanisms of a common form, each having two sets of type and impression cylinders and so combined as to permit the perfecting of two webs, each the full width of the machine, or the printing of a plurality of narrow webs, with a number of impressions on one or both sides,

this figureshowing the course of the two full width webs in perfecting simply, that is, printing one impression on each side- Fig. 2 is a similar view showing the course of the webs in printing two webs of less thali flill width, one being perfected simply'andlthe,

other printed with five impressions on 'one side and one on the other. Fig. 3 is a similar view showing'the course of the latter web alone. Fig. 4 is a plan view corresponding to Fig. 2. Figs. 5 to 8 show another construction embodying my invention. Fig. 5 is a view similar to Figs. 1 to 3, showing the courseof the webs in printing two webs of less than full width, one web being printed with four impressions on oneside and one on the other, and the other with three colors on one side. Figs. 6 and 7 are similar views showing, respectively, the course of the former and latter webs alone. Fig. 8 is a plan view corresponding to Fig. 5.

Referring now to Figs. 1 to 4, A, B, and O, D, are the two sets of type and impression cylinders forming one full width web perfecting-mechanism, and E, F, andG, H, the 'corresponding sets of type and impression cylinders of a second full width web perfecting mechanism, A, O, and E, G, being the respective type cylinders and provided with inking mechanisms I of any suitable form. These web perfecting mechanisms may be provided with separate deliveries if desired, or may constitute each a separate machine, the web being led from one to the other in color printing, but they are shown as forming a duplex web machine and having a common delivery K which may be of any suitable form capacitated to deliver products of different widths, that shown having the pair of longitudinal folders and the slitter commonly employed in double width machines, each half of the divided web, single or two ply, being folded by its respective folder. With these web perfecting mechanisms, I combine-inthe construction shown in Figs. 1 to 4 a webreverser and transferrer L and a web reverser M. These parts may be of any suitable construction, so that the web transferrer and reverserwill operate to transfer the web fromone end of the type and impression cylinders to the opposite end and reverse it simultaneously, and the reverser operates to reverse the web without transferring. As shown, the web transferrer and reverser L is a common 'web turner consisting of two converging a web reverser being shown and fully described in my Patent No. 212,444 so as to need no further description here.

The paths of the webs are as follows: In perfecting-two full width webs, as shown in Fig. 1, .the first web a: is led around conducting rolls 1,2 and downward between the first type and impression cylinders A, B, then around cylinder B and upward between the second type and impression cylinders G, D, whence the perfected web passes to the delivery mechanism K. The second web 1 passes upward between the first type and impression cylinders E, F of the other web perfecting mechanism, then around the impression cylwhich is divided longitudinally into two narrow Webs which are led to their respective longitudinal folders. In printing two half width webs, one perfected simply, or printed in but one color on each side, and the other in five colors on one side and one on the other, as shown in Fig. 2, the first mentioned web y is led over one end of the type and impression cylinders E, F, and G, H, in the usual manner. For convenience this web is shown as led over the rear ends of these cylinders, and the web as over their front ends, but it will be understood that this may be varied. In printing the web a: in five colors on one side and one web is led to and between the rear ends of r the cylindersA,B, and C, D in the usual manner, then passes around the impression cylinder D to and under the conducting'rollfiand around -web reverser and transferrer L, by which the web, perfected at the rear ends of the cylinders A, B, and O, D,-is-reversed=and transferred to the front of the machine, thence over the cylinder B between'it-and type cylinder A, receivingfrom the front ends of cylinders A, B a second color on the side which received the second or perfecting impression, thence directly to the type and impression cylinders E, F, whereby a third color is imprinted onthis side, thence around cylinder F and between it and impression cylinder 'H past the web transferrer and reverser L between cylinders D, *E, and over conducting roll 6 to and around the web-reverser M, by which the web is reversed'with'out transferring,-t-hence over the conducting rolls 7, 8 to and between the cylinders O, -D, whereby a fourth color is imprinted by the front ends of these cylinders,-thence directly to the cylindersG, I-I, receiving a fifth color, whence the webnowprinted with five colors on one side and one on the other passes over the conducting rolls 3, 4 to the delivery mechanism K and is folded by one of the longitudinal folders thereof, while the otherweb y abreast web a: on the rear of the machine is folded by the other longitudinal folder. In this construction, the five colors are'upon the side which side and one on the other the web will be led to and between cylinders A, B and-C, D,

at the rear of the machine, as before, thence directly to thecylinders G, H, around cylin der H, to and around roll and the transferrer L,-,by which it is transferred to the front 5 of the machine, thence to and between cylinders A, ,B, and directly to the cylinders E, V F, and out over rolls 3, 4, to the delivery mechanism. If three colors on one side and one-on the other of web a: be desired, the web, printed and perfected by the cylinders A, B, and O, D, will be led, at the rear of the machine, to and around the web reverser and transferrer L'andthence, at the front of the machine, directly to the web reverser M and r 5 to cylinders G, D, and G, H, and out as above described, or the reversal by the reverser M may be omitted and the web led from the web reverser and transferrer L directly to the. cylinders G, D, and G, H. -If a web printed in four colors on one side only bedesired, the web m at. the rear of. the machine may be led from cylinders A,B, around the cylinder B. to the reverser M, thenceto thecylinders O, D, thence about the web reverser and z 5 transferrer L andto the front ends of the cylinders O, D, and G, H. 1

Many other variations may be made and many. modificationsin the construction shown may readily be devised by those skilled in the art.

In Figs. .5 to 8 I have shown a modification employing two perfecting mechanisms of the samekind as shown in Figs. 1 to 4in combination with two web reversers and transfer- 5 rers, the construction beingv shown in these figures as printing and deliveringassociated together two webs ofless than full width, the webx being printed with four colors on one side and one on the other, and the web y with three colors on one side only. The path ,of the webs in thisconstruction is asfollows: The web w is led tothe type and impression cylinders A, B, and O, D at the rear of the machine, as previously described, th us being per- 5 fected, thence to the cylinders G, H and over the conducting roll 9 and web reverser and transferrer N, by. which the web is reversed and transferred to the front of the machine, thence about the impression cylinderH and under the conducting rolls 10, 11 to cylinders A, B, thence to cylinders E, F and out over the roll. 12 to the delivery mechanism K, printed with four colors on one side and one on the other. The web y is led to the cylinders E, F, at the rear of the machine, thence around the cylinder F, over the reverser and transferrer O, by. whichv the web is reversed and transferred to the front of the machine, thence over the conducting roll 13 to the cylinders O, D, and G, H and out under rolls 3, 4, to the delivery mechanism K, printed in three colors on one side only and associated with the web m, If two webs, each printed in three colors on one side and one on the other, are desired, the web a: will .be led to the cylinders A, B,

andO, D, and perfected thereby, thence led to the cylinders G, H, then reversed and transferred to the front of the machine by the re-' verser and transferrer-N and led about the I impression cylinder F and between it and cyl- 7o inder E. The Web y will be led to'the cylinders E, F, at the rear of the machine around the cylinder F to the reverser and-transferrer K O, thence to cylinders A, B, andO, D, and G,

H, at the front of the machine and'out, associated with the web a: as before. i

It will be understood that,in the production of all the products described, the webs may be led to the opposite ends of the cylinders from those stated, and that the descrip tion of the webs as led to the rear or front is only for convenience.

Many other constructions embodying my invention may readily be devised by'those skilled in the art, such constructions being varied in accordance with the result desired.

It will be understood, therefore, that my invention is notto be limited to any of the specific arrangements shown, nor to the specific form of any of the printing mechanisms or Of'thB 0 web controlling devices combined therewith, but that the formand arrangements of the parts may be varied widely without depart ing from myinvention.

It is evident that the web controlling devices may readily be located as shown so as not to interfere with the lead of the webs in perfecting, enabling the construction tobe used for web perfecting or color printing-with out other change than the lead of the web, but I00 it will be understood that this is not absolutely essential,-but that the invention may be embodied in a construction in which the web controlling devices must be-removed or thrownout of position for 'web perfecting.

It will be understood that the web perfect: ing mechanisms combined with web controlling devices to embody myinvention may form independent machines, or may be combined in a single machine printing from a plurality L of webs, as shown. The mechanisms shown are adapted to perfect double width webs or to print in colors single width webs, and it, will be understood that the term half width and less than half width used herein refer [15 not to the size of the page but to the capacity of the printing mechanisms, and the inven-' tion may be embodied in machines printing" webs of any width according to the products desired.

What I claim is 1. The combination with a'pluralityof web perfecting mechanisms, of web controlling devices co-acting therewith to present a web of less than full width to different parts'of the 12 5 same printing devices, whereby a plurality of impressions may be printed upon'the'same side of a single web from the different mechanisms, substantially as described. Y

2. The combination with a plurality of web perfecting-mechanisms, of web controlling de vices co-acting therewith to present-a'web of less than full Width to different parts of each ofthe printing devices, whereby two webs of less than full-width may be printed and a transferrer eoa'eting therewith to present said webto different parts of the same printing 1 5 devices, and a web 'reverser coaeting therewith to reverse the web between impressions, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing -20 witnesses.
